Moreover, if atheism is true, there is no moral accountability for one’s actions. Even if there were objective moral values and duties under naturalism, they are irrelevant because there is no moral accountability. If life ends at the grave, it makes no difference whether one lives as a Stalin or as a saint. As the Russian writer Fyodor Dostoyevsky rightly said: “If there is no immortality, then all things are permitted.”
–William Lane Craig
The existence of objective moral values and duties serves as a valuable piece of philosophical evidence. We typically don’t have to be told that murder, stealing, theft is immoral because it is self evident. God has written a transcendent moral law on our hearts so that we know that an objective moral standard exists. Without an objective standard, how can we truly measure whether an action is morally good or evil with objectivity? Some declare that morals are merely subjective and dependent on the individual person or society. However, when someone steals their car they’ll be the first complaining about how immoral stealing is. Just remind them, ‘that person must believe stealing is morally permissible so you really shouldn’t be upset’. Moral relativism is truly unliveable. If you don’t believe me, look in the history books and see how many millions of people died under the morally relativistic atheistic dictatorships of the 20th century.
